Servo

writeMicroseconds()

Writes a value in microseconds (uS) to the servo, controlling the shaft accordingly.

The function write() call writeMicroseconds(), mapping the values of 0 to 180 degrees to a microsecond value of 544 to 2400.

// SYNTAX
servo.writeMicroseconds(uS)

On standard servos a parameter value of 1000 is fully counter-clockwise, 2000 is fully clockwise, and 1500 is in the middle. The default values of 544 to 2400 match Arduino devices. Note however that attempting to drive a servo past its endpoints (often indicated by a growling sound) is a high-current state, and should be avoided.

Continuous-rotation servos will respond to the writeMicrosecond function in an analogous manner to the write function.
